"ETF has been a valuable investor and partner for many years. As with any early stage company there have been difficult times, but ETF stayed calm and provided support as we revised our strategy. They really understand the dynamics of a growing technology company and have been very supportive in providing access to their network of contacts. I consider Perpetuum to be very fortunate to have them as an investor. The result is that Perpetuum is now growing rapidly, becoming a global leader in its market and continually increasing value."
